UNITED STATES PATENT i FFTCE.

D. W. LEVIS, OF JANESVILLE. VISCONSIN.

PUlVLP.

Specification of Letters Patent No. 32,881, dated July 23, 1861.

To all whom it may concern:

Be it known that I, D. Vif. Lnwrs, of the city of Janesville, in thecounty of Rock and State of Wisconsin, have invented a new and ImprovedMode of Constructing and Operating a Balancing Force and Litt Pump; andI do hereby declare that the following is a full, clear, and exactdescription ot' the construction and operation ot the same, referencebeing had to the accompanying drawings, making a part of thisspeciiication, like characters referring to like parts in each iigure.

Figure l, shows a side view of the pump, in elevation, inserted in awell, shown in vertical section. Fig. 2, represents a full size verticalsection of the pump cylinder E, Fig. l, and shows the generalconstruction of the same, and fully represents the peculiar combinationof the lower pin and wing valve M, with the strainer F, which isattached to the lower part oit the cylinder' E, by screwing it into thesame, as there represented. Fig. 3, is a ull size vertical section,representing` that part of the stationary pump case, which is attachedand secured to the planking A, that covers and protects the mouth of thewell WT, and also the upper and movable part C, to which is attached thewater pipe D, thus connecting the upper and movable part of the pumpcase C, with the piston L. F 4, represents a 'uil size clutch band H,which is secured to the pipe D, by the key U. said band forming a scatfor the equalizing lever gage G, which is secured to the clutch banciii, by the bolt g. Fig. 5, represents the equalizing lever gage at fullsize. Fig. 6, represents a full size clutch band secured to the pipe D,by the key U', forming a guide for the balancing rod O, which is securedto the equalizing lever gage G, by the bolt f, at the top, said rod O,passing through the clutch band J, at z', to the cresu cent shaped plateK, which is attached to the piston barrel E, by the rods L Fig. 7 is afull size section on the line X, Y, Fig. 2, showing the plan of the wingvalve M, and the location of the pin N. Fig. 8, represents a full sizeplan of the crescent shaped plate K., and the iiange L, which forms apart of the piston. f

The pump is operated by raising the lever or handle S, which has anoscillating fulcrum R, which is pivoted at the point Q on the bolt af,thus raising the movable case C, the pipe D, and the piston L, and atthe saine time, and by the same motion, causing the piston barrel E, todescend by means ot' the balancing rods P, O, which are attached andconnected to the piston barrel E, by means of the crescent shaped plateK and the rods i, thus causing a double stroke with one motion of thelever or handle S. Wvhen the lever, or handle, descends, the motion otthe several described parts is reversed, and the water made to iiow outat the orifice V. Li order to balance the pump, the pipe D is to beiilled with water, and if found to be too light, or out of balance thetop of the rod P is to be carried in toward the tulcrum rod E, and thebolt c moved to the hole 7L or L, and at the same time the top of therod O is to be carried out on the equalizing lever gage G, and the boltf moved to the hole a.. Ti' the water pipe is found to be too heavy, areverse movement of the several described parts is to be made.

l do not claim new the construction of the pump cylinder, nor the pinand wing valve, nor the construction of the pump case in two parts; but

I do claiml. The peculiar combination of the piston L, and piston barrelE, with the equalizing bar or lever gage G and the balancing rods P. O,substantially as and for the purpose -set forth and described.

2. The oscillating fulcrum bar R, combined with the lever or handle S.and the balancing rods P, O, and the movable case C, substantially asshown and described.
